C.J. Miller LLC

What C.J. Miller LLC does

C.J. Miller LLC is a family-owned full-service site development and asphalt paving contractor headquartered in Hampstead, Maryland, founded in 1959 and now in its third generation of Miller family ownership. The company operates four modern asphalt plants across three sites in Finksburg (two plants), Westminster, and Woodsboro (Keymar), producing over 100 different hot mix asphalt designs along with cold patch, porous/permeable pavement mixes, bulk emulsified asphalt, virgin aggregates, sands, topsoil, and recycled materials. Its vertically integrated production incorporates recycled asphalt products (RAP) technology, and the company maintains over 15,000 tons of crushed stone at each of two locations, over 2,000 tons of screened topsoil, and 125,000+ cubic yards of fill material, supported by a fleet of more than 40 dump trucks.

The company's service offering spans the full site development value chain: clearing, demolition, earthwork (including mass grading), soil cement stabilization, site utilities, road construction, asphalt paving, stormwater management, and reclamation, alongside specialty services such as hydro excavation, vacuum truck work, stone shooter material placement, and roll-off dumpster rental in 20, 30, and 40 cubic yard sizes. C.J. Miller serves three primary verticals — government/educational institutions (including Baltimore County Public Schools and Montgomery County), commercial developers (such as the 1 million+ square foot West Oak Ridge warehouse project), and residential developers (including the Creekside Hamptons East and Patuxent Greens communities) — plus independent contractors as material purchasers. Geographic service territory covers Maryland, Pennsylvania, Virginia, West Virginia, Delaware, and Washington D.C.

The business model combines project-based professional services revenue with unit-based materials revenue (asphalt/aggregate sold by ton or cubic yard), hourly truck and dumpster rental income, and transaction-fee disposal revenue at the Finksburg recycling facility. Pricing is quote-based for projects and unit-based for materials, with no public price sheet; customer acquisition relies on direct enterprise field sales, long-term relationships with general contractors (including 30+ year relationships), and industry association memberships (AGC, Maryland Asphalt Association since 1954, PAPA, others). The company employs 251-500 people and remains wholly family-owned with no disclosed institutional investment.
